Power over Ethernet (PoE) refers to a technology that transmits power through network cablesM. POE is the abbreviation of Power Over Ethernet, Chinese translated as active Ethernet, is not to change the existing network structure, in the case of some IP-based devices to transmit signals at the same time to provide power to it.
POE means Power over Ethernet technology. The following is a detailed explanation: Basic concepts of POE technology POE, full name of Power over Ethernet, is an Ethernet-based power supply technology. It allows data to be transmitted over Ethernet while also providing power to devices connected to the networkSupplied. In the traditional Ethernet architecture, the device needs to connect the network power and data lines separately.
POE (Power Over Ethernet) refers to the existing Ethernet Cat.5 cabling infrastructure without any changes, while transmitting data signals for some IP-based terminals (such as IP telephones, wireless LAN access points AP, network cameras, etc.). Technology that can also provide DC power for such equipment.
The POE function refers to the power supply Ethernet. Explain in detail nextPOE function: Basic definition of POE function POE, full name of Power over Ethernet, it is a technology that transmits data through Ethernet, but also can provide DC power supply for connected devices. The core idea of this technology is to transfer data and power simultaneously on the basis of existing Ethernet cabling, without the need to lay out a separate power cord for the device.
POE is short for Power over Ethernet, meaning power over Ethernet. POE technology allows data and power to be transmitted over Ethernet cables, which means that network devices can be transferred(such as IP cameras, wireless access points, IP phones, etc.) connect directly to Ethernet without the need for additional power lines. POE technology simplifies the installation and deployment of network equipment, and improves the flexibility and reliability of equipment.

Since learning English,So I named the four seasons of the year. Spring is called "warm", summer is called "hot", autumn is called "cool", winter is called "cold". Maybe the name of autumn is cooler, I have a little affection for it. In high school, the Chinese teacher said that the hometown of autumn is the most beautiful season of the year. I didn't really believe it. I was skeptical. But from then on, I began to observe autumn and feel autumn.
Fireworks, also known as fireworks, fireworks, fireworks, firecrackers, according to the "China fireworks standard - Safety and quality" of fireworks are defined as: fireworks as raw materials, used for productionEntertainment products that produce sound, light and color. Invented earlier by the working people of China, it is often used in grand ceremonies or performances. In fact, the structure of fireworks and firecrackers is similar, and its structure contains black powder and powder.Four fingers held out and pronounced in English: Four...

Folded up; Ending; When used as an adverb, it means to fall down; Flip; Through; Complete coverage; Used as a preposition to mean: above; Travel through.
2, on ear is a headset clipped to the ear, usually the kind of headset is not big over ear is the kind that wraps the ear, in terms of comfort this is better. Sound quality depends on headphones, and varies from person to person.
3, OTA is a new type of technology in the headset industry, its full name is Over-The-Air, meaning air upgrade. This technology can improve the performance and functionality of the headset through wireless signals, directly upgrading the firmware of the headset without the need to connect to a computer. This technology brings a more convenient and efficient upgrade method for the headset industry, but alsoLet's explore each of these uses. When describing an action, emotion, or result, over- usually means over, over, or beyond the normal range.
2. "Over" is an English word used primarily as a preposition, adverb, and adjective. Its basic meaning includes "in... Above ", "over", "over", etc. It has different uses and meanings in different contexts. As a preposition, "over" can be used to indicate a position or place above an object. For example, "The book is over the desk".
3, the direction can be "from or through..." Top (talk, etc) "solution; Make from Edge overflow, overflow "solution, and then generally connected to container objects, river banks and so on. over can also represent a state of being. Above, over... On top, prostrate... "Block on..." In front, covered by... The first "solution.
4, over can also represent the state, as "covered in... Above, over... On top, prostrate... "Block on..." In front, covered by...

5. Above, right above We live over a small bookstore. We live above a small bookstore. (cover) in... We spread a carpet over the floor. We carpeted the floor. Over... A plane flew over the house. Ne flew over the house.
exceed The most common meaning of Over is to exceed a certain amount or degree. For example: I have over 100 books. I have more than one hundred books. In this usage, over means the number over 100. The end. Over can also mean to end something or a stage. For example: The war was over. The war is over. What is above?
The reason for saying "OVER" : to tell the other party that the words are finished, to avoid misunderstandings when transmitting information, and to ensure the integrity of the transmitted information.
Walkie-talkie over is a communication term that indicates that a conversation has ended and the communication frequency can be released for others to use. In radio communication, "over" is a very common expression used to refer to a radio, radio, or other communication deviceThe speaker's speech is finished. The way over is used is sometimes combined with sign language, facial expressions, and other voice tone changes to enhance expression.
The last word from the walkie-talkie is always over, telling the other party that the words are finished, to avoid misunderstandings when passing on information. In short-wave communication must say over, because short-wave communication through the ionosphere reflected, the signal strength is often unstable, so the use of the silence will be turned off, at this time if not over it is not easy to know each other's information finished.
PoE is the full name of Power over Ethernet, that is, power over Ethernet, is a technology that transmits power through Ethernet cables. The basic principle is that by transmitting AC signals in an Ethernet cable, DC power is loaded onto the cable, and then the power is transmitted through the cable to a device at the other end of the network. PoE makes use of the characteristics of network transmission only AC connection, without DC connection, so as to achieve device power supply.
PoE device is divided into power supply end (PSE) and power receiving end (PD), both based on IEEE standards for connection, implementationDevice power supply. PoE system includes PSE device and PD device, PSE device provides power to PD device, PD device receives power supply.
PoE power supply is divided into Endpoint PSE (fully standard equipment) and Midspan PSE (providing power in the Ethernet cable). These devices are not only responsible for data transmission, but also power the end device, as shown in Figure 11. Depending on the rate and connection mode, there are multiple options such as 10/100BASE-T and 1000BASE-T. The position of PSE determines the type of power supply, there are four, while PDThe device must be compatible with all power supply modes to ensure safe operation.
PoE power supply: Power over Ethernet, that is, network cables. Data and power can be transmitted on the same network cable. Principle: When the device that needs to be powered is connected to the PoE power supply device, the power supply device will detect whether the device supports PoE power supply, and it will start to power supply until 48V stable power supply, not that it will not power supply.
The main difference between PoE and non-POE is the power supply mode. Devices with PoE can transmit data and power simultaneously over a network cable, while devices without PoE require itIndependent power supply. PoE (Power over Ethernet) technology allows network devices to receive power over standard Ethernet cables.
